My invention relates to improvements l'in dump cars.

It is an object of my invention to improve the dumping doors of cars; valso the means associated therewith for supporting the doors vin closed position and for y-releas'- ing the saine.

'It is also an objectof my inventionto 'provide supporting'means for dump car doors which will release in unison, and to provide means whereby the locliing'of one element in a plurality of associated locking elements will also lock other elements in theseries.

Otherand flirtherobjects of the invention will more fully and'cl'early appear from the description and claims hereinafter following.

In the drawings 'Figure 1 is a side lelevational viewof a pa'rtof a Vcar showing my improved construction incorporated therein. Figure 2 is a vertical vsectional View taken through the car and Vshowing slightly more than one half thereof, said section being takenl on a line corresponding substantially to the line 2-2 of lFigure 1. Figure 3 is a View of the door locking 'mechanism shown in Figure 1, on an enlarged scale. Figure 4 is a vertical sectional view through Lthe'outer end of 'the door, and is taken on a line correspondingto the line Llf-ll'of Figure 3` In said drawings A denotes the side of Ithe car; B the "center sill construction; Cfcrossbeams extending 'outwardly from the sills tothe sideofthe `c'ar; C bolstersal-so'eX- tending acrossthe car; D a vdumping door hinged lto the center sill, vhaving lprojecting floor beams E-EeXtendin-gbeyond the free edge thereof; F and G designate the door supporting means adaptedfto respectively engage therespective floor-bean1s E-E lof the door to maintain' l'the door in locked position; H a connection between "the respective means F and Gto canse the lockingelements to function in unison: and -J designates the door supporting member adapted toyarrestf the-*downward Imovement of the door.

`The yside A of the car is shown as com` posedi'of planks ."carried a- 'frame which preferably includes a Alower 'chord Vmember 10, having ja horizontally Vdisposed vflangejll, and a vertically eXtending `flange '12, the flange 11 resting upon the'ends ofthe crossb'e'arns and holsters. ,Side stakes '13 rise vertically' from Ithe `ends vofr the 'crossbe'ams Vor holsters, 'each Vbeing secured to lits `respectiv'e cross member and to ithe lflange Y12. Thediagonal members 'of 4the lside wall `aire indi'- c'ated at 14,-and a gusset 15 is'shown esconnectin'g onel of thedia-gonal members with the verticalstake 13. Thecenter sill B 'preferably includes two channels 16-"16 having a cover plate A17 connecting the'saine` Each crossbearn C consists lof a shallow diaphragm 18, with a su'rmounting `cover plate 19,' eX? tending lfrom side lto side `0f the car. The bolsterdiaphragms 118 Aare formed 'of a soinewh'at deeper section Ythan those "of the crossbeams and are `connectedy across 'the plane of the center sillby a' bottom plate218- The'dumping door D is'preferably formed' of metal as shown, lhaving 'a series of rigidifying emboss'ments 2O in I'the formof ctrrugations preferably 'pressed above lthe plane of the door plate-and extending from the hinged end of thedoor :towards the free edge thereof. The marginsofthe'door are flanged at the side vv'edges asjat 21, 'andat the front and 'rear edges as indicated at 22 and Q3, 'respectively. Each d'oor is Lpivtally mounted at its 'rear on ythree 'hinge butts 24, secured to 'the center sill, there beingja corresponding 'nunrber 'of 'hinge 'straps 25 onfthe `deor, which 'extend through the rear AflangeY Q3 thereof, each strap 25 being 'formed with "a hinge "eye 26 'thrugh which 'the pivot pin 27 estende to connect the same with its vcor responding hingebjutt 24. Thehin'ge straps 2.5 adjacent the 'Side 'dg'S 'Of 'the ldoor aie united to the door 'with longitudinally eX- tendi'ng vreinforcing angle shaped 'niei'nbers 1:26 which extend towards the free end of the door 'ja-'11d connectwith thejflnge of `4 a bar 127, which feirtends from side edge to side edgeiof the door.k

The' outer orfswnging 'edge :of the door supported from the car through the medium ofthe 'dooj'r supporting "means F fand G, 'en'-v gaging the outer 'ends of 'the 4door beams vThe l'door 'supporting Ymeans F sand G, respectively, include 'shouldered latch elements 44 and 45, pivotally mounted in brackets `vrespec'tively indicated Lat 46 "and "The bracketr, preferably "a casting, is 'provided with 'angularly related walls "including la main back wall' 48, 'and Ya horizontally "eX-l tendingw'all 49, said wal-ls ywhen the bracket i'sin position, 'being "adapted `to Ibear against the respective flanges 12 and 11 of the lower chord of the side, and being securely riveted thereto. To provide a housing, and also provide against outward bending or movement of the latch, the bracket 46 is formed with an outer wall or web 148 united to the main back wall 48 by a wall 50 of irregular contour which provides front and rear limiting stops as indicated at 51 and 52 respectively for the latch member 44, which is pivotally mounted at 53 and adapted to have swinging movement between said walls 48 and 148. The latch member 44 is formed with a shank 53 having the upper portion thereof sloping downwardly from its pivotal support and away from the corresponding floor beam E. At the bottom of the shank is provided a shoulder or curved bearing face 55 which is formed to correspond substantially to the curve of the ledge 42 on the beam E, said latch member below said shoulder 55 being formed with a depending handle 56, and intermediate the handle 5G and the shoulder 55, the latch is formed with a tapered face 57 adapted to be engaged by the related door beam E to displace the latch out of the path of said beam, the door moves towards closed position, it being understood that the respective latches 44 and 45 are formed and mounted to normally gravitate to locking position.

rIhe latch element 45, forming part of the supporting means G, is similar to the latch 44 exceptthat it is not provided with an operating handle, the same being connected with the latch 44 by means of a bar I-I, said bar having one end pivotally connected to the member 44, between the jaws 58-58 formed integrally therewith, and the connection of the bar H with the latch 45 is effected by extending the end of the bar between the walls 60-60, similar to the walls 58-58, of the member 45 and loosely securing the same by means of a pivotpm 59. The latch 45 is adapted to have lswmging movement independently of its companion member 44, due to the Aprovision of a slot 61 formed in the end of the member H, through which the pivot 59 extends. The braclret'47 is in many respects similar to bracket 46 except that itis extended rearwardly of the hook, and a locking cam 62 is pivotally mounted between its inner and outer walls. The cam 62 is adapted to lock the latch 45 when it is in locking position beneath the door beam, and when said hook 45 is locked, it also operates to lock the other of said hooks, due to the fact that` both hooks in the series are disposed to swing in the same direction and are inter-connected by means ofthe member H. Similarly in releasing the doors, the release of member 44 will release both of said hooks simultaneously. Thus it will be noted that the simple connection provided forthe pair of hooks,

eliminates one releasing device and one locking device for each door, and at the same time assures safety to the operator, as the handle 56 is conveniently located to one side of the door, and the operator may stand out of the path of the discharging load when releasing' the doors.

I/Vhile I have herein shown and described what I now consider the preferred manner of carrying` out my invention, the same vis merely illustrative and I contemplate all changes and modifications that come within the scope of the claims appended hereto.
